    Scoot revving to the max, and just not going any faster? Seem like your engine is just running too high? Need that extra top speed boost? Performance gear set gets your going. Gear ratio is a 49/17T, which is 2.88. Potential of up to 10mph top speed increase! Taiwanese quality, at a Chinese price. Simple press fit can be done by anyone with simple tools and skill. This gear ratio is the best compromise between take off acceleration and top speed. Other kits make you bog coming off the line.
    These are for the 139qmb 4stroke 50cc chinese scooter and atv engines with standard or big bore.
